1. Precise Measurement: Our refractometer is an optical precision instrument designed for measuring the zing point of antize. It utilizes the principle of total reflection to accurately determine the refractive index of the solution, enabling precise calibration of the concentration and performance of the test fluid. 2. Versatile Applications: This refractometer can measure the zing point of ethylene glycolbased and propylene glycolbased antize solutions, as well as the zing point of automotive windshield washer fluid. Additionally, it can check the specific gravity and condition of leadacid battery electrolytes. 3. Temperature Compensation: Equipped with automatic temperature compensation, our refractometers ensure accurate measurements within a temperature range of 10°C to 30°C. This feature guarantees reliable and consistent results even under varying environmental conditions. 4. Clear Scale and High Accuracy: The refractometer features a clear, easytoread scale for quick and precise measurements. With its high accuracy, the measurements provided by our refractometers are extremely reliable.
